<p>Make sure your escaping the HTML characters</p>

<p>E.g.</p>

<pre><code>// Always check an input variable is set before you use it
if (isset($_POST['contact_list'])) {
    // Escape any html characters
    echo htmlentities($_POST['contact_list']);
}
</code></pre>

<p>This would occur because of the angle brackets and the browser thinking they are tags.</p>

blocks|key|3908887|text|删除你的一些textarea类，比如|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3908888|<textarea+name="Address"+rows="3"+class="input-text+full-width"+placeholder="Your+Address"+></textarea>|code-block|syntax|javascript|3908889|至|3908890|<textarea+name="Address"+rows="3"+class="full-width"+placeholder="Your+Address"+></textarea>|3908891|这取决于您的模板(购买的模板)。开发人员已经包含了一些JavaScript来从UI上的正确对象中获取值，但是像input-text这样的类只能找到$('input[type=text]')，这就是为什么。|offset|length|style|CODE|3908892|entityMap^0|0|0|0|0|1J|A|21|L|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|W|8|@$M|X|N|Y|O|P]|$M|Z|N|10|O|P]]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|11|8|@]|9|@]|A|$]]]|R|$]]

<p>Remove some of your textarea class like</p>

<pre><code>&lt;textarea name="Address" rows="3" class="input-text full-width" placeholder="Your Address" &gt;&lt;/textarea&gt;
</code></pre>

<p>To</p>

<pre><code>&lt;textarea name="Address" rows="3" class="full-width" placeholder="Your Address" &gt;&lt;/textarea&gt;
</code></pre>

<p>It's dependent on your template (Purchased Template).
The developer has included some JavaScript to get the value from correct object on UI,
but class like <code>input-text</code> just finds only <code>$('input[type=text]')</code>, that's why.</p>

blocks|key|3909005|text|这很简单。只需在textarea标签之间编写php值代码即可。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3909006|<textarea+id="contact_list">+<?php+echo+isset($_POST['contact_list'])+?+$_POST['contact_list']+:+''+;+?>+</textarea>|code-block|syntax|javascript|3909007|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

<p>it is very simply. Just write your php value code between textarea tag.</p>

<pre><code>&lt;textarea id="contact_list"&gt; &lt;?php echo isset($_POST['contact_list']) ? $_POST['contact_list'] : '' ; ?&gt; &lt;/textarea&gt;
</code></pre>


<p>I am using php to get textarea value using post method but getting a weird result with that let me show you my code</p>

<pre><code>&lt;form method="post" action="index.php"&gt;
    &lt;textarea id="contact_list" name="contact_list"&gt;&lt;/textarea&gt;
    &lt;input type="submit" name="submit" value="Send" id="submit"/&gt;
&lt;/form&gt;
</code></pre>

<p>I am entering some names and their email address in the textarea, and everytime i echo the value or textarea it skips the email address and only showing the name let me show the way i am entering value in textarea</p>

<pre><code>"name1" &lt;name@email.com&gt;, "name2" &lt;name2@email.com&gt; 
</code></pre>

<p>and once I will echo using php it will only echo the name and will skip the email address.</p>
